THREE-WAY cock;

To all'whom it-may-concem: p

Be it known that l[,- Jorm V. MInLER, a citizen of the United States, and a resident of East Orange, in the county of Essex and State'of- New Jersey, have invented a oer tain new and useful Three-Way Cock, of which the following is a description.

' My invention relates to pipefco'nnections and more specifically to a three-way cock primarily designed for use in pipe systems in (ivvhi'ch' acids or other chemicals are carrie My object is to provide a noveland efii-, cient device of this character not acted upon by chemicalsior other fluids passing therethrough; and with this object in view, my invention contemplates the use for all parts with which such fluids are brought .into contact of a material which is not aifected thereby. As illustrative of my invention l and a valve therefor made of porcelain or earthenware, the remaining parts of the said device being so located as not to be contacted by the fluids.-

Another object of my invention is to provide a strong and eflici'ent pipe connection wherein a body is provided with means to prevent lateral shifting of the members for fastening the pipes in place, thereby insuring a proper registration of the said pipes and the passages in the body. It has heretoforebeen common to provide devices of this character with openings extending through the body for holding the fastening members in place,- but these devices have been found difficult to make and liable to break when the fastening members for the pipes were drawn tight. These objections I avoid by forming the holding means for ghe fastening members exteriorly of the ody.

Other objects of my invention will, appear more fully in the following specification and ap ended claims.

n-prder that my invention may be more.

Specification of Letters Patent.

In all the views like parts-are designated by the'same reference numerals.

- and lower surfaces of the body are two par- Patented name, this. Application filed March 1 2,191.11. serial No. 611,823.-

designates a a'llel .grooves or recesses Land 4'- respectively, and projecting from the same surfaces are two parallel ribs or projections 5 and 5' respectively As shown in the drawings, the grooves 4' and 4: are placed parallel to the main passage 2 and the projections 5 and 5 parallel to the by-pass 3; but it is v obvious that the directions of the" grooves and projections may be interchanged or otherwise altered.

Rotataply mounted in'the body 1 and hav- 'ing transverse openings 6 and 7 at right angles to each other for regulating the flow through the main passage 2 and the bypass 3 is a porcelain or earthenware valve 8 having a square upper portion 9 for engagement with any desired turning means. I

As shown in Fig. 3 the pipes 10, 11 and 12 which are preferably made of lead or some other material not acted upon by chemicals,

are provided with integral outwardly extended flanges I3, 14 and 15 respectively. These pipes are secured to the member -1 by metallic flanges 16, 17, 18, 19 and fastening members, preferably bolts, 20, 21, 22 and 23, each of the flanges 16, 17 and 18 belng provided with a central aperture and an enlargement at the base of the said aperture to receive a pipe and the flange thereof respectively. The apertureand enlargement of the flange '17 are shown at'2k and 25 respectively in Fig. 3. In order that the ends of the pipes may be held firmly 1n engagement withthe body, the plpe flanges are made of a sufiicient thickness to extend slightly beyond the inner surfaces of the securing. flanges In assembling my improved device, the shanks of the bolts 20 and which secure the flanges 16 and 17 in position are placed in the grooves 4: and 4 and, as the nuts 26 and 27 on these bolts are drawn tight to clamp the flanges in position with the pipes in register with the main passage, thesebolts are held from displacement laterally the bolts22 and 23 for the flanges 1 8 and 19 in place, while these bolts are being drawn tight, the latter are placed in engagement with the outer sides of the projections 5 and 5 respectively as is clearly shown in Fig. 2.

It'is evident from the above description that the pipes, 10, 11 and 12 are held in intimate contact with the member 1 and that in no part of my coupling is the chemical permitted to contact any parts that might be affected thereby. It is also evident that by reason of the location of the fastening bolts for the flanges, exteriorly of the earthenware body member 1, the latter is permitted to retain approximately its-full strength.

Having now described my invention what I claim and desire to protect by Letters Patent of the United States is as follows:

1. As an article of manufacture, a threeway cock comprising a body having a main passage therethrough and a by-pass leading from said main passage to the exterior of said body, said body having exteriorly thereof a plurality of parallel grooves, a valve mounted in said body and controlling the flow through said main passage and said by-pass, and means including a plurality of fastening members, for securing a plurality of pipes in register with the ends of said main passage and the outer end of said bypass respectively, some 'of said fastening members being located in said grooves and the others on the upper and lower surfaces of said body, substantially as described.

2. As an article'of manufacture, a threeway cock comprising a body of a material unaffected by chemicals, said body having a main passage therethrough and a' by-pass leading from said main passage to the ex terior of said body and having exteriorly thereof a plurality of parallel grooves, a valve also of a material unaffected by chemicals mounted in said body and controllin the flow through said main passage and sai by-pass and means including a plurality of fastening members for securing a plurality of pipes in register with theends of said main passage and said by-pass respectively, some of said fastening members being located in said grooves and the others on the upper and lower surfaces respectively of I said body, substantially as described.

3. As an article of manufacture, a threeway cock comprising a body having a main passage therethrough and a by-pass leading from said main passage to the exterior of said body, the'latter having exteriorly thereof a plurality of parallel grooves and a plurality of parallel projections at an angle to said grooves, a valve mounted in said body and controllin the flow through said main passage and said bypass, and means including a plurality of fastening members for securing a plurality of pipes in register with the exterior 0 the ends of said main passage and the outer end of said by-pass respectively, some of said fastening members bein located in said grooves and the remain er being 10- catedon said body in engagement with said projections, substantially as described.
